copy the sign then add :)
Add their magnitudes, and keep the same sign for the sum.
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
If the larger of the two integers is negative, then their sum is negative, regardless of the sign of the smaller one.
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
In mathematics, the rule that says "two negatives make a positive" is based on the concept of multiplication. When you multiply two negative numbers together, the negative signs cancel each other out to give a positive result. This rule is consistent with the properties of arithmetic and helps maintain consistency in algebraic calculations.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
alright i think this is rightSTEPSSame DIFFERENT1)Add 2)subtract3)larger number sign(-,+)is answer sign
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
-- If the two integers have the same sign, their quotient is positive. -- If the two integers have different signs, their quotient is negative.
Add the number together and give the answer the same sign as the numbers.
Write the difference between them, and give it the sign of the one with the larger size.
You subtract the smaller from the larger and give the answer the sign of the number with the larger absolute value.
